In recent days, Shandong Zaozhuang 67 year old man was pregnant naturally and gave birth to a daughter, which made many people call it magic. What is the limit of the latest age of human birth? At present, the oldest woman in the world is mangayama from India. She gave birth to twin daughters in vitro at the age of 74 in the past few months.
After all, it is rare to promote a mother at the age of being a grandmother, but it is indisputable that since the beginning of the new century, the childbearing age of mothers has been continuously postponed, from the first child before the age of 25 to almost 27. As a result, the time for giving birth to two or more children was postponed for another two years. Todays young people are faced with urging marriage as soon as they graduate and giving birth as soon as they get married, which is largely a collision of the two generations concept of childbearing.
Why there are so many old mothers
The term old woman refers to a woman over 35 years old.
When giving birth to a first child, she is an old woman for a variety of reasons. Some have delayed their life process because of reading, some have no time to take personal life into account in their career, some have wasted too long in a wrong long-distance love run, some small families cant afford to have children in their early years due to economic stress, some dont want to have children lose their freedom, some dont want to have children, but finally compromise under the pressure of parents and family
Zhang Zhiwei, deputy director of obstetrics at the First Affiliated Hospital of Shandong First Medical University, said: the majority of elderly mothers are still two children, and the number of elderly women in their first pregnancy is relatively small.
More people are classified as elderly mothers only when they have two children. Their reasons are much more unified: in 2015, the comprehensive two child policy was implemented, and some women were catching up with the last bus of golden age of childbearing, which led to the birth of more elderly women in obstetrics, some even over 40 years old.
The two child policy has fulfilled the birth wishes of some people.
In the statistics of the elderly mothers in the first maternal and infant health care hospital affiliated to Tongji University, before the implementation of the fertility policy in 2013, the proportion of the elderly mothers was nearly 15%, mainly giving birth to the first child; during the period of the two child policy in 2015, the proportion of the elderly mothers increased to 17%, of which just over half were given birth to the second child; during the period of the comprehensive two child policy in 2017, the proportion of the elderly mothers further increased to nearly 22%, of which the proportion was given birth The second child already dominates.
What seems unfair to men and women in childbearing is that according to Jiangsu health care, the best childbearing age is 25-29 for women and 25-35 for men. Men have five or six years more at ease than women.
Although with the growth of age, the elderly women have better economic strength, but the body is more difficult to bear.
First of all, the success rate of pregnancy is not high and abortion is easy. The rate of spontaneous abortion among women aged 35 and over was three times higher than that of women aged 20 to 29.
In the survey of six obstetric institutions in Haidian District and Chaoyang District of Beijing from November 2016 to February 2017, those who were over 40 years old were divided into super old group, 35 to 39 years old group, and those under 35 years old group were divided into non old group.
The risk of hypertension, diabetes, postpartum hemorrhage and placental related diseases in super old and old women were significantly higher than those in non old women.
With the increase of age, the content of nitric oxide in pregnant women decreased and oxidative stress increased, which led to the poor vasodilation of endothelium and induced the occurrence of pregnancy induced hypertension. The increase of age will also lead to the decrease of islet compensatory function and the insufficiency of placental blood perfusion, which will increase the risk of gestational diabetes.
8.5% of the babies in the super old age group were sent to NICU after birth, which was 4.7% and 3.7% in the old age group and the non old age group;
4.5% of the infants in the super elderly group suffered from respiratory distress syndrome, 2% and 1% in the elderly group and the non elderly group, respectively.
Its not easy to have a mother or a baby after 35. In addition to the physical burden, we also face the real difficulties of parents getting older and unable to help raise their babies, the interruption of childbearing during the rising period of middle-aged career, and the refusal of older children to accept the second child. To the old mother, the world may as well be more gentle, more love.
